Definitions
- the present invention relates generally to vending machines. More particularly, the present invention relates to a method and apparatus for dynamically managing inventory pricing of a vending machine.
- Vending machines are well known and have existed since the late 1880s.
- the first vending machines were rudimentary devices primarily designed to dispense cigarettes and postcards.
- Modern vending machines are employed to store and dispense a vast array of merchandise in response to a customer request and appropriate payment.
- merchandise includes drinks, candy, frozen deserts, snacks, video tapes and children's toys.
- vending machines are generally considered to have significant advantages over traditional merchandising. Specifically, vending machines enable the automated sale of merchandise at unconventional locations and times; and they do not require sales personnel.
- vending machines Although the basic advantages of vending machines are significant, prior art vending machines have several significant disadvantages when compared to traditional merchandising, particularly relating to inventory control and pricing.
- a first disadvantage is the difficulty of maintaining an inventory of perishable items.
- a second disadvantage is the difficulty of selling or “turning over” an inventory of low demand items or items of inferior quality.
- vending machine patent prior art examples include the following U.S. patents: U.S. Pat. No. 4,412,292, entitled “System for the Remote Monitoring of Vending Machines;” U.S. Pat. No. 4,654,800, entitled “Control and Monitoring Apparatus for Vending Machines;” U.S. Pat. No. 5,091,713, entitled “Inventory, Cash, Security, and Maintenance Control Apparatus and Method for a Plurality of Remote Vending Machines;” U.S. Pat. No. 5,367,452, entitled “Mobile Merchandising Business Management System which Provides Comprehensive Support Services for Transportable Business Operations;” and U.S. Pat. No. 4,282,575, entitled “Control and Monitoring Apparatus for Vending Machines.”
- These inventions generally disclose remote monitoring systems, currency control systems, and data collection systems designed to address shortcomings of prior art vending devices.
- Non-patent prior art includes VendMaster's software product entitled “Windows for Vending PRO with Inventory.” This product enables a vending machine operator to report and analyze various historical sales data. VendMaster's product is intended to enhance a vending machine operator's ability to identify high-demand inventory, determine preferable times to stock the machine and calculate suggested prices.
- the aforementioned solutions generally attempt to solve inventory problems by allowing operators to monitor and analyze raw sales data. These solutions fail to adequately address the aforementioned shortcomings of present vending machines. Specifically, the prior art fails to provide adequate solutions to the problems of maintaining an inventory of perishable items; increasing inventory turnover; and recovering the investment in low demand or inferior quality items.
- the present invention addresses such problems by providing an apparatus and processing approach that have not previously been proposed.
- the present invention provides a method and apparatus to automatically and dynamically determine, adjust and manage product pricing in a vending machine to account for current market trends.
- a method for automatically managing a price of a product in a vending machine. The method includes the step of receiving a product identifier specifying the product. The method further includes the step of receiving inventory data. The inventory data includes the quantity of the product in the vending machine.
- the method includes the step of determining price management data associated with said product.
- the price management data specifies supply and demand data associated with the product.
- the method continues with the step of determining the price for the product, and storing the price management data and the price.
- This first method of managing inventory pricing is particularly useful if performed upon stocking the vending machine.
- An apparatus is also disclosed for performing the steps of first method.
- a second method for automatically managing a price of a product in a vending machine.
- the second method includes the step of accessing price management data and inventory data associated with the product.
- the inventory data and price management data are used, in part, to form the basis for the price in the step of determining the price of the product.
- the determined price is then stored in a memory and preferably displayed.
- This second method may be performed in response to a particular event, such as a product sale, a change in the environment, or according to a schedule.
- An apparatus is also disclosed for performing the steps of the second method.

- FIGS. 5A , 5 B and 5 C illustrate the contents of an exemplary price management table 500 .
- Each of the twelve illustrative records 548 - 570 of price management table 500 represents information pertaining to a specific product and item dispenser. For purposes of illustration, this data is based on a system date of Jul. 1, 1997.
- the data stored in price management table 500 falls into three categories: inventory data, shown in FIG. 5A ; evaluation data, shown in FIG. 5B ; and pricing data, shown in FIG. 5C . Certain data elements may fall into more than one category, as described below.
- Each record in price management table 500 includes a dispenser identifier 510 and a product identifier 512 .
- Dispenser identifier field 510 stores a dispenser identifier that uniquely identifies a corresponding item dispenser 122 of vending machine 100 .
- Product identifier field 512 identifies the product associated with the dispenser identified by field 510 .
- each dispenser dispenses only one product, and each product is limited to a single dispenser.
- a dispenser dispenses only one product, and each product is limited to a single dispenser.
- the remaining fields shown in FIG. 5A store data generally describing the inventory of vending machine 100 .
- Stocked quantity field 514 stores the number of items that were originally stocked in the dispenser identified by field 510 . The contents of this field are input by an operator during stocking or routine maintenance.
- Available quantity field 516 contains the number of items currently associated with the dispenser identified by field 510 . After stocking or routine maintenance, the contents of field 516 is automatically set equal to the contents of field 514 , for each record corresponding to a restocked product. Thereafter, the available quantity is automatically updated by CPU 126 for each associated item sold.
- Current price field 518 contains the selling price of the product associated with the item dispenser.
- Current price field 518 may be populated by the operator during stocking or routine maintenance, and may be determined according to the process steps of the present invention. Exemplary process steps which may be executed to automatically determine a current price are described with reference to FIGS. 6-8B .
- FIG. 5B illustrates fields of price management table 500 that define when a price is dynamically evaluated.
- Stock date field 520 stores the date the dispenser identified by field 510 was most recently stocked.
- Termination date field 522 contains the last date on which the items of the associated dispenser may be sold. The termination date is entered by an operator during stocking of vending machine 100 and may be a date entered by the operator, the expiration date of the items in the associated dispenser, or another relevant date, such as the next scheduled stocking date.
- the next two fields of price management table 500 define shelf times for the product identified by field 512 .
- Total shelf time field 524 defines the maximum allowable shelf time for the product.
- the contents of field 524 are calculated by CPU 126 based on stock date field 520 and termination date field 522 upon stocking.
- Remaining shelf time field 526 defines the remaining shelf time of the product and is periodically calculated by CPU 126 based on the system date, and the contents of field 522 .
- Evaluation frequency field 528 stores a code representing a rule defining the frequency with which the CPU 126 should evaluate the price of the product identified by field 512 . Although field 528 only contains a code, the contents of field 528 illustrated in FIG. 5 show the logical representations of the codes.
- the evaluation rule applicable to a product is generally selected by an operator from a set of rules defined by the vending machine manufacturer. In the examples shown in FIG. 5 , evaluation frequency field 528 may store a code representing a rule to evaluate a product price every x purchases or a rule to evaluate a product price every y hours, where x and y are greater than zero.
- a rule could be defined to evaluate the price whenever sensor 115 senses a predetermined condition. If sensor 115 is a thermostat, CPU 126 could be programmed to evaluate the price whenever the temperature exceeded a predefined temperature. Other evaluation frequency rules could be implemented to evaluate the price when demand for a product rapidly changes or if at the current demand level items will remain stocked past the termination date in field 522 . Further, CPU 126 could be programmed to evaluate prices during periods of low activity, such as during the early morning.
- Last evaluation date/time field 530 stores a timestamp identifying the time of last sale
- field 532 stores the number of sales of the associated product made since the last price evaluation.
- Fields 534 - 538 define demand-based price evaluation parameters.
- Previous demand field 534 stores the level of demand as of the last price evaluation.
- Current demand field stores the current demand level for the product in the dispenser identified by the contents of field 510 .
- CPU 126 periodically calculates the current demand and stores it in field 536 . After each evaluation, CPU 126 sets the contents of previous demand field 534 equal to the contents of current demand field 536 .
- Demand increment field 538 defines the incremental difference between the previous demand and the current demand that is required to trigger a price evaluation process.
- FIG. 5C illustrates fields of price management table 500 that are used to calculate the current price stored in field 518 .
- Price adjustment increment field 540 stores the amount by which the price of the product identified by field 512 may be adjusted. Of course, the price of the product identified by field 512 may be adjusted by multiples of the price adjustment increment.
- Fields 542 - 546 define price parameters for the product identified by field 512 .
- the minimum price to be charged for the product is stored in minimum price field 542 ;
- the manufacturer's suggested retail price for the product is stored in suggested price field 544 ;
- the maximum price to be charged for the product is stored in maximum price field 546 .
- the manufacturer's suggested retail price of field 544 may be used as the initial current price after stocking, or it may be used as a factor to determine future prices.
- the minimum price and maximum price fields 542 and 546 are used to prevent the calculated price from falling outside a predetermined range. This financially protects both the vending machine operator and the consumer.
- FIGS. 6A-6B , FIGS. 7A-7B and FIGS. 8A-8B illustrate the process steps executed by vending machine 100 to determine a price of a product at each of these times, respectively.
- CPU 126 receives a request to update price management table 500 .
- This request indicates that an operator is stocking vending machine 100 , and the request includes an operator identifier and authorization code entered by the operator.
- CPU 126 retrieves a record from authorization table 400 using the received operator identifier as an index.
- CPU 126 compares operator identifier and authorization code received at step 610 with the contents of operator identifier field 402 and authorization code field 404 retrieved at step 612 , respectively. If the comparison yields a match of the respective data, CPU 126 proceeds to execute step 620 , otherwise, CPU 126 denies the operator access to price management table 500 .
- CPU 126 receives input from the operator.
- the operator inputs a dispenser identifier, a product identifier and relevant portions of the inventory, evaluation and pricing data pertaining to the stocked product and associated dispenser to be stored in price management table 500 .
- the inventory data received from the operator includes a stocked quantity, and a current price.
- the evaluation data received from the operator includes a termination date, an evaluation frequency and a demand increment.
- the pricing data received from the operator includes a price adjustment increment, a minimum price, a suggested price and a maximum price.
- the data received from the operator is stored by CPU 126 in the appropriate fields of price management table 500 . Of course, receiving data for one or more of these fields from the operator may be optional as CPU 126 could supply default values for certain fields.
- the data for one or more of these fields could be automatically received from a remote source using the network configuration illustrated in FIG. 9 or from an attached bar code reader (not shown) such as the U.P.C. scanners attached to the vending machines manufactured by Automatic Vending America, Inc.
- CPU 126 calculates the remaining price management data to be stored in price management inventory table 500 . Specifically, CPU 126 calculates the total shelf time, remaining shelf time and current price for the associated product. Although, the current price may be input by the operator, the current price would preferably be set equal to the manufacturer's suggested price stored in field 544 . Of course, in an alternate embodiment, the current price could be determined in accordance with the price evaluations described below with reference to the post-purchase evaluation process and the periodic evaluation process.
- the stocking process concludes with the step of adjusting the price display 124 corresponding to item dispensers 122 dispensing the associated product.
- the price displays 124 are adjusted to display the price determined at step 620 .
- CPU 126 receives a customer request to purchase an item.
- the request includes an indication of payment and a dispenser identifier.
- the request may include a product identifier instead of the dispenser identifier.
- CPU 126 uses the received dispenser identifier to retrieve the relevant record from price management table 500 , as shown at step 712 . Based on the contents of field 516 , a determination is made at step 714 whether sufficient inventory is available to honor the request.
- CPU 126 processes step 716 and causes change dispenser 118 to return any inserted payment, and the transaction is terminated. If vending machine 100 holds sufficient inventory to honor the request, CPU 126 processes step 718 and activates item dispenser 122 corresponding to the dispenser identifier received at step 710 .
- CPU 126 updates the price management data pertaining to the product selected by the customer and stores the updated data in price management table 500 .
- the step of updating includes the step of decrementing the contents of available quantity field 516 , incrementing the contents of field 532 to reflect the sale and updating the contents of current demand field 536 .
- a determination is made whether the necessary events have occurred to require a price evaluation for the selected product. In the present embodiment, this step includes comparing the parameter identified by evaluation frequency field 528 to either last evaluation date/time field 530 or sales since last evaluation field 532 . If it is time to evaluate the price of the selected product, CPU processes step 726 .
- CPU 126 calculates the change in demand for the specified product and at step 728 compares the calculated change in demand to the demand increment data stored in field 538 . If the demand for the specified product has changed by at least the demand increment stored in field 538 , CPU 126 processes step 730 and determines a new current price for the specified product.
- the new current price equals the contents of current price field 518 plus the contents of price adjustment field 540 . If the demand for the product has decreased, the new current price equals the contents of current price field 518 less the contents of price adjustment field 540 .
- CPU 126 verifies that the new current price falls within the range of acceptable prices as defined by minimum price field 542 and maximum price field 546 .
- current price field 518 is updated to reflect the new current price as shown at step 734 . It is important to note that although a specific price determination formula has been described herein, the method and apparatus of the present invention is intended to work with many different price determination formulas applicable to product pricing. Various formulas may easily be implemented by one of ordinary skill in the art with minor design variations. Finally, at step 736 , CPU 126 updates the price display 124 associated with subject item dispenser to reflect the new current price of the product.
- FIGS. 8A and 8B a flow chart is presented illustrating the exemplary process steps that may be executed to determine the price of a product during a periodic price evaluation.
- the process steps of FIGS. 8A and 8B are described herein with respect to a single product. It is envisioned that these steps will be repeated for each product represented in price management table 500 .
- CPU 126 begins the periodic price evaluation process by retrieving a record associated with a specified product from price management table 500 .
- CPU 126 accesses the contents of evaluation frequency field 528 to determine if the price evaluation frequency is based on time, as shown at step 814 . If the evaluation of the product's price is not based on time, the process ends. Otherwise, the process proceeds to step 816 .
- step 814 may include determining whether the quantity of the product is non-zero. If the quantity of the product is zero, CPU 126 would terminate the process to avoid evaluating the price of an unavailable product.
- CPU 126 determines the time elapsed since the price of the product was last evaluated. This is accomplished by retrieving the system date and time from clock 132 and comparing the system date and time to the date and time stored in last evaluation date/time field 530 . At step 818 , the result is compared to the evaluation frequency parameter indicated by field 528 . If sufficient time has elapsed, the process proceeds with step 822 . Otherwise, the process ends.
- CPU 126 calculates the change in demand for the specified product and compares the calculated change in demand to the demand increment data stored in field 538 . If the demand for the specified product has changed by at least the demand increment stored in field 538 , CPU 126 processes step 826 and determines a new current price for the specified product.
- This formula determines the new current price based on the remaining shelf life and the maximum and minimum price boundaries.
- the calculated price may be rounded to the nearest price adjustment increment indicated in field 540 .
- current price field 518 is updated to reflect the new current price as shown at step 830 .
- CPU 126 updates the price display associated with subject item dispenser to reflect the new current price of the product.
- record 562 illustrates the result of process 800 .
- record 550 is associated with a dispenser stocked with cola.
- the remaining shelf time for the cola in inventory is 62 days, while the total shelf time stored in field 524 is 70 days.
- the maximum price for cola, stored in field 546 is $1.15, and the minimum price is $0.35, as shown by field 542 .
- the price evaluation formulas discussed with reference to FIGS. 7A-7C and 8 A- 8 B rely on data collected and stored in price management table 500 .
- the present invention may employ other factors in place of or in addition to stored data to determine a current selling price.
- output from sensor 115 may be used to determine the price of a product.
- a price calculation could be employed that increases the price of a soft drink as the external temperature increases.
